Key concepts

3 concepts

  1. 1

    The heart's chambers include the right atrium, right ventricle, left atrium, and left ventricle, which are separated by atrioventricular valves.

  2. 2

    The tricuspid valve (or right atrioventricular valve) and the bicuspid (or mitral or left atrioventricular valve) are attached to chordae tendineae and papillary muscles to prevent backflow of blood.

  3. 3

    The three layers of the heart are the epicardium, the thick myocardium, and the thin endocardium, with plate-like structures called trabeculae found within the muscle.
